Privacy and data processing
Effective Date: September 15, 2026 · Last Updated: September 21, 2026
What to understand before submitting data
- Email checks process the addresses you submit and may perform domain lookups.
- Submitted addresses can appear in debug logs. Diagnostic processing can involve an external service when configured.
- An in-memory scoring engine does not establish a service-wide promise about storage, logs, retention, or third-party processing.
1. Email checks and contact lists
Address checks analyze submitted email addresses and return scores and supporting signals. Domain lookups may be required. The presence of debug logging means that an address submitted for checking is not guaranteed to remain only in memory.
Submit only data you are authorized to process. Confirm the service’s operational data-handling terms before connecting a production list.
2. Bounce diagnostics
Bounce diagnosis processes supplied error messages, which may contain email addresses and other personal data. The implementation supports configured external diagnostic processing.
Remove unnecessary personal information from diagnostic text. Confirm enabled processors and their handling of diagnostic content before production use.
3. Accounts, billing, and usage
Account, authentication, billing, and usage records are separate from the email-scoring engine. Their existence means that the service as a whole should not be described as having no stored data.
We use an email-identity fingerprint to prevent repeated free-account allowances. Deleting an account does not reset eligibility during the current calendar month in UTC. Its fingerprint may remain after account deletion for this abuse-prevention purpose.
Use the account and billing interfaces for available account actions. For questions about account records or deletion, contact [email protected].
4. Operational details and privacy inquiries
For questions about active logging, storage locations, retention periods, deletion, enabled processors, security controls, or contractual data-processing terms, contact [email protected] before submitting production personal data.
This description does not assert a compliance certification, a universal no-retention guarantee, or a particular security configuration.
